An agreement between two countries to promote and protect each other's investments, allowing an investor to sue the host government directly through international arbitration.
A Bilateral Investment Treaty is an agreement between two countries to promote and protect investments made by investors of each country in the other's territory. A BIT typically guarantees fair and equitable treatment, protects against unlawful expropriation, and provides for Investor-State Dispute Settlement (ISDS) — a mechanism allowing an aggrieved investor to bring the host government to international arbitration. India's template for negotiating such treaties is the Model BIT adopted in 2015, which the Union Finance Ministry is currently reviewing with a view to making it more investor-friendly while safeguarding India's sovereign regulatory space.
Type: TreatyFair and equitable treatment — the host state must not treat a covered investment arbitrarily or in bad faith.
Protection against expropriation — investments cannot be taken over unlawfully or without due process and compensation.
Investor-State Dispute Settlement (ISDS) — an investor may initiate international arbitration directly against the host government, without needing its home state to take up the claim.
Enterprise-based definition of investment — India's 2015 Model BIT protects investments held through an enterprise rather than adopting a broad asset-based definition.
Local remedies requirement — the 2015 Model BIT requires an investor to exhaust domestic legal remedies for at least five years before commencing international arbitration.
Limited remedies — a tribunal's power under the 2015 Model BIT is confined to awarding monetary compensation.
Carve-outs — government procurement, taxation, subsidies, compulsory licences and national security are excluded to preserve the government's regulatory authority.
Frequency: Investment treaties, FDI trends and ISDS appear regularly in UPSC Mains GS Paper 2 and 3, and in banking general awareness.
| Aspect | Bilateral Investment Treaty | Trade Agreement |
|---|---|---|
| Primary focus | Protection of investments | Trade in goods and services |
| Who can bring a dispute | The investor, directly against the host government | Only the governments, state-to-state |
| Forum | International arbitration under ISDS | State-to-state dispute settlement machinery |
| Exposure for the state | Greater legal exposure, since private parties can sue | Greater diplomatic flexibility |
India's approach to investment treaties changed after it lost its first investment arbitration. The 2015 Model BIT was drafted to reduce that exposure, and the current review reflects a further shift as India becomes a significant capital exporter as well as importer.
White Industries takes India to arbitration, arguing that inordinate delay in Indian courts in enforcing an arbitral award violated the India-Australia BIT.
The tribunal rules against India — its first adverse investment treaty award — having found that the judicial system failed to deal with the claim over more than nine years.
India adopts a new Model BIT, with an enterprise-based definition of investment, a five-year local remedies requirement and significant carve-outs.
The Union Finance Ministry reviews the 2015 Model BIT; a revised text is expected to be placed before the Union Cabinet.

$95 billion — a record
Nearly $44 billion
Less than $1 billion
About $7 billion

$34 billion
The numbers explain the policy shift. Gross FDI reached a record $95 billion in 2025-26, yet net FDI had fallen to under $1 billion in 2024-25 before recovering to about $7 billion — because repatriation and outward investment now offset much of what comes in. Over the same period Indian firms' overseas investment rose from $11 billion to $34 billion. That changes what India wants from a treaty. Historically India negotiated as a capital importer, seeking to limit investor claims against itself, which is why the 2015 Model BIT emphasised local remedies and carve-outs. But those same restrictive terms slowed treaty-making, since several developed countries were reluctant to accept the model — and they now also limit the protection available to Indian companies investing abroad. The review therefore considers a negative-list approach, keeping only critical sovereign concerns non-negotiable while offering flexibility elsewhere. For a Mains answer, the tension to articulate is between regulatory autonomy and treaty attractiveness.
A BIT protects investments between two countries and allows investor-state arbitration (ISDS).
BIT disputes are investor-state; trade agreement disputes are state-to-state.
India's template is the Model BIT of 2015, under review in 2026 by the Union Finance Ministry.
2015 Model BIT: enterprise-based definition, five-year local remedies rule, monetary compensation only, carve-outs for taxation, procurement, subsidies, compulsory licences and national security.
White Industries v India (2011) — first adverse award against India, under the India-Australia BIT.
Gross FDI hit a record $95 billion in 2025-26, but net FDI fell to under $1 billion in 2024-25.
ODI rose from $11 billion (2020-21) to $34 billion (2025-26).
A BIT protects investments and lets an investor sue the host government directly through international arbitration. A trade agreement covers trade in goods and services, and disputes under it are settled between governments.
Investor-State Dispute Settlement is the mechanism in a BIT that allows a foreign investor to bring a claim against the host government before an international arbitral tribunal.
Chiefly because it requires an investor to exhaust local remedies for at least five years before going to arbitration, and it excludes matters such as taxation and government procurement. Several countries were reluctant to accept the model, which slowed India's treaty-making.
White Industries Australia Limited v Republic of India (2011) was India's first adverse investment treaty award. The tribunal found India in breach of the India-Australia BIT because Indian courts had failed to deal with the company's claim over more than nine years.
Because Indian companies are investing heavily abroad — Overseas Direct Investment rose from $11 billion in 2020-21 to $34 billion in 2025-26 — so future treaties must also protect Indian investors overseas, not only shield India from claims.
